v WINDW` VENTILATOR Filed-May 15, 1944 Patented Apr. 23, 1946 WINDOW vENrILATon William V. lBarrowclough, Cadillac, Mich., assignor to Insulated Windows, Inc., a corporation of Michigan Application May 15, 1944, Serial No. 535,727 2 claims. (c1. sas- 97) Y My invention relates to a new and useful irnprovement in a window ventilator adapted for mounting in windows of various types, including storm windows.

It is an object of the present invention to provide a ventilator of this class formed from a single piece of fabric and having louvers or deilecting plates extending longitudinally thereof and normally inclined tc the horizontal, the spaces between which may communicate with transversely disposed outlet openings.

It is another object of the present invention to provide a ventilator of this class having the longitudinally extending louvers communicating with the vent openings and connected together and to the main body at the space between the openings.

Another object of the invention is the provision of a ventilator of this class which is simple in structure, economical of manufacture, durable and easily and quickly installed.

Other objects will appear hereinafter.

It is recognized that various changes and modications may be made from the detail of structure illustrated and it is intended that such shall be encompassed within the scope of the claims which form a part hereof.

Forming a part of this specification is a drawing in which,

Fig. 1 is a -front elevational View of a window showing the invention applied;

Fig. 2 is a sectiona1 View taken on line 2 2 of Fig. l, slightly enlarged;

Fig. 3 is a rear elevational view of the invention;

Fig. 4 is a sectional view taken on line 4-4 of Fig. 3, slightly enlarged;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4

Fig. 6 is a fragmentary front elevational view with parts removed;

Fig. 7 is a sectiona1 view, slightly enlarged, taken on line 'I-'I of Fig. 3.

In the drawing, I have shown the invention applied to a window, embodying the side rails 8 and 9 and the end rail I0. The ventilator plate II is provided on its upper edge with a tongue IIa interlocking with a tongue 'I2 on the lower rail 13. Formed in the front or outer face of the plate I I are a series of spaced apart slots I 2 which extend longitudinally of the plate II and are inclined, as clearly shown in Figs. 4 and '7. By forming these slots I2 in spaced relation, the louver or shutter-forming members I4 are thus formed. The inner face of the plate Il is cut out to provide a channel I5 in which is, slidably mounted a closure plate YI8 having the vknob I8a mounted thereon. Fixedly mounted in the channel I5 at opposite ends, to serve as abutments for the slidable closure I8, are the closure plates I6 and I'I. Extending transversely of the plate II are formed, on the inner face of the channel I5, the transverse openings 2D which are cut inwardly deep enough to communicate with the spaces I2. Formed in the slidable closure I8 are openings I9 corresponding in size and spacing to the openings 20. The construction is such that when the slidable plate I8 is slid so that its openings i9 register with the openings ZIJ, air may pass through the openings I9 and 26 and through the spaces or channels I2 which lie between the louvers or shutters I4; When the slidable closure I8 is moved so that its openings I9 do not register with the openings 20, the ventilator may be said to be closed, as shown in Fig. 5. In Fig. 6, I have illustrated a front elevational view with the slidable closure plate I8 removed so that the formation of the openings 20 more clearly appears. It will be noted that there is a rib I3 between each of the openings 20 and, as shown clearly in Fig. 7, this rib I3 is integral with the,

louver or shutter-forming member It. Consequently, these members I4 are free from connection at the openings 2|), as clearly appears in Fig. 4, but are not disconnected at the space between the openings 20. These members I 4 are formed of quite thin material and if they were to be stretched over a wide expanse to cover a wide window opening, they would have a tendency to sag if they were loose throughout their length. With this method of formation, however, they are con.`

nected integrally with the member II between each opening 20 and a strong, durable structure is thus provided.

This method of construction also lends to an economical manufacture of a ventilator of this type. A routeringoperation is resorted to in 0rder to form this channel I5. The spaces 20 and the louvers I4 are formed by a routering operation. The openings 20 are then routered from the face I5 extending inwardly until they meet the members I 4 so that when looking at the openings 20 from the front with the slide I 8 removed, the shutters I4 are visible, as clearly appears in Fig. 6 and Fig. 4. The method of mounting and securing the slidable plate I8 in position is also a simple and eifective one requiring a minimum amount of labor operations.

What I claim as new is:

1. A window ventilator of the class described,

comprising: an elongated plate having a plurality of horizontally directed vertically spaced apart slots formed inwardly from one face of said plate and extending inwardly of said plate a distance less than the thickness of said plate to provide a plurality of spaced apart horizontally directed louvers integral with said plate, there being a horizontally directedchannel formed in the opposite face of said plate, extending from end to end thereof and being of less depth than the thickness of said plate, said plate having a plurality of horizontally spaced apart vertically directed narrow slots formed inwardly thereof from the base of said channel a distance less than the thickness of said plate and inwardly of said plate a suflicient distance to communicate with said slots between said louvers; a slide plate slidably mounted in said channel and having a plurality of spaced apart vertical slots formed therein and slidable into and out of registration with said vertically directed slots in said plate; and means at opposite ends of said channel for limiting slidable movement of said slide plate in said channel.

2. A window ventilator of the class described, comprising: an elongated plate having a plurality of horizontally directed vertically spaced apart slots formed inwardly from one face of said plate and extending inwardly of said plate a distance less than the thickness of said plate to provide a plurality of spaced apart horizontally directed louvers integral with said plate, there being a horizontally directed channel formed in the opposite face of said plate, extending from end to end thereof and being of'less depth than the thickness of said plate, said plate having a plurality of horizontally spaced apart vertically directed narrow slots formed inwardly thereof from the base of said channel a distance less than the thickness of said plate and inwardly of said plate a suicient distance to communicate with said slots between said louvers; a slide plate slidably mounted in said channel and having a, plurality of spaced apart vertical slots formed therein and slidable into and out of registration with said vertically directed slots in said plate.
